No idea on the white material unless they put a layer of fiberglass cloth sandwhiched in between the fiberglass mat. Fiberglass cloth is very strong - just not good for finished surfaces.
It's better to not go through the gelcoat than it is to go through it - but it's not fatal. All fiberglass bodies need quite a bit of blocking work and having to take down a high area, through the gelcoat is common. Epoxy primer will seal it off before paint.
